Adam Clarke on Mark 5:19

Suffered him not - Ὁ δε Ιησους, Howbeit Jesus, is omitted by ABKLM, twenty-seven others, both the Syriac, both the Persic, Coptic, Gothic, Vulgate, and one of the Itala. Mill and Bengel approve of the omission, and Griesbach leaves it out of the text.

Go home to thy friends, etc. - This was the cause why Jesus would not permit him to follow him now, because he would not have the happiness of his relatives deferred, who must exceedingly rejoice at seeing the wonders which the Lord had wrought.
